Yes. National Australia Bank connects through CDR Open Banking (via Fiskil), so you can link your accounts and start syncing in minutes.

How often does NAB sync to Zerosum?

Syncs are event-driven: NAB notifies Redbark via CDR webhooks when new data is available, and your Zerosum updates soon after, within a few hours of a transaction posting, with no fixed polling schedule.

Is my NAB connection read-only?

Yes. Redbark requests read-only access under the CDR. It can read transactions and balances, and can never move money or change your NAB accounts.

Does Redbark store my NAB data?

No. Redbark uses a pass-through architecture: your NAB transactions are proxied live to Zerosum. We store consent records, encrypted tokens and minimal account metadata, never transaction amounts, descriptions or balances.

Is Redbark independently security tested?

Yes. Redbark was penetration tested in July 2026 by Project Black, a CREST-accredited Australian security firm, covering the web app, REST API, MCP server and admin console. The test returned zero critical and zero high-risk findings, and every finding raised was remediated and confirmed closed on retest.

Which Zerosum plan supports NAB sync through Redbark?

Zerosum’s bring-your-own-provider bank sync is included with Plus and Pro, including the Pro trial. Redbark Developer is 30% off while your Zerosum connection stays active.

Will Zerosum duplicate my NAB transactions?

Zerosum runs SimpleFIN imports through its normal review, matching and duplicate-prevention flow. You control which NAB provider accounts are linked to each budget account.
